Each of these walkie talkies stands at a diminutive 2 by 1.5 inches, but work up to 150 feet apart and penetrate walls, floors, steel, and concrete. These utilize a push to talk function, with an additional Morse code function. Flexible 4 inch antennas are safe and won't impede the portability of these tiny walkie talkies. Includes button batteries.
